BRUSH.

Application filed August 2.7, 19%. Serial No.y 131,844.

This invention relates to cleaning devices, but has particular relation to brushes of a type somewhat similar to that disclosed in Letters Patent No. 1,517,492 issued to us on the 2nd day of December, 1924, andthe present invention, and said pateiited'device have similar uses and like objects, which are fully set forth in the aforesaid patent and need not be enumerated herein.

Our present invention, has, as a further object tov improve the construction of that disclosed in our aforesaid patent; by providing more eiiicient means for binding togethertlie cleaning members or bristles of the brush; by affording such means which shall be more readily applied to the bunch or group of said bristles or cleaning members.; vby furnishing binding,r i'n'eans for the cleaning' members, located thereon in a manner whereby a variety of types of the brush may be readily made, in order, that these types may be constantly kept on hand to meet the demands or to suit the selection of. customers.

lVith the above named object-s, and with those set forth in our aforesaid patentin view, the present invention consists inV certain peculiarities of the construction, novel arrangement and combination of the parts thereof asV will be hereinafter more fully set forth and specifically claimed.

Besides the objects hereinbefore referred to, other advantages and objects of the present invention will be disclosed in the following, description and explanation, which will be more readily understood when read in conjunction with the accompanying drawing, which illustrates embodiments of which the invention is susceptible, it being understood that modifications and changes may be resorted to without departing from the spirit of the invention, so loner as they fall within the scope of the appended claims.

In the accompanying dra-wing Fig. 1 is a view in side elevation of a brush constructed according to one form of the device.

Fig. Q is a view partly in section and partly in elevation of a slightly modified forni of t-lie invention, showing the bristles or cleaning members by dotted lines and the binder broken and partly in elevation.

Fig. 3 is a detached perspective view of the form of either binder shown in Fi grs. 1 and 2 before it has been creased or flanged and Fig. 4 is a cross sectional view taken on line 4-4 of F ig. 1 looking in the direction indicated. by tlie arrows. i

Corresponding numerals of reference refer to like parts throughout the different views of the drawing. i Y Referring; now, more particularly toFifgs. 1 and 2 of the drawing, the brush is made up or comprises a bunch or group of fibrous' members 5 ot a suitable length, which iiiembers are by preference the dried roots of rice plants, but we desire it to be understood tha-t we do not limit ourselves to the use of said material. These members as shown inFig.

1 are crinlrled or provided with irregular uni dulations and are placed. alongside of each other and formed into a cross-sectionally circular bunch or group, between the ends offwh'ich is securely positioned at any desired point a binder which holds the members very closely together at the point at which they are bound by the binder, but allows them to' flare outwardly towards each end as shown,

unless the binder shall be positioned close tofr one of the ends of the bunch or group of the cleaning` members or bristles 5, in which latter position it is manifest the vbinder will hold them closely together only at the point where primarily is in the shape of a short section of4 'a pipe or a continuous band, as shown in Fig.

3, is formed with the corrugations. the depressions 8. will toa certain extent be embedded in the mass of members 5 and some of said members will occupy the inner cavities of the corrugations and thus firmly hold the bristles or cleaning members 5 in their grouped positions.

l7l7hile we have shown in Fig. 1 `of the drawing. the binder 6 located at the middle of the brush, yet. it will be understood that it may be located near one of the ends of the bristles or cleaning' members 5 or at any intermediate point between that which is shown and one of the ends of the bunch of bristles or cleaning members, thus affording more flexibility between the ends of the longer lll) bristles or cleaning members and the adj acent end of the binder, besides this construction will ali'ord dili'erent types of the brush which may be selected by the customer, either for its appearance or on account of the said greater flexibility.

Again referring to Fig. l, ot the drawing, shorter bristles or cleaning members 5 may be employed by placing the binder 6 on the bunch thereof so that its end nearest the transverse line am@ may be about flush with the ends of the bristles, which may terminate at said line a-a, yet extend through the binder, thereby forming the flared portion extended from its other end.

In Fig. 2 of the drawing, we have shown a slight -modilication in the construction of the binder, as well as, in the location thereof on the bristles or cleaning members, which modiication consists in employing as betere the band or pipe section 6, which, in the lirst described construction as well as in the modified form now under consideration, may be made of any suitable material but preferably of aluminum or some kind of a metal that will not corrode. This modified form consists in providing each end of the binder G' with an inwardly extended annular groove 9 and outwardly thereof with a slightly outturned flange 10, all of which is clearly shown in Fig. 2 of the drawing. lhen this construction is used, as well as when the irst described construction is employed, the band 6 in its plain form as shown in Fig. 3, is lirst placed on the bristles or cleaning members vat the desired location or place thereon, and is then provided with the annular groove and flange at each end of the band 6, by any suitable instrument or means, and the corrugations or cleats 7 and corresponding depressions 8 are formed in the first described construction by any suitable kind of a machine or means tor producing the same.

It will be understood by reference to Fig. 2 that that portion of the cleaning members 5 or bristles lying between the ends of the binder will exert themselves outwardly so as to bend or bulge towards the middle of the periphery of the binder, and it will also be understood that the cleaning members or bristles outside of the binder will iare towards their free ends, in which construction it is apparent the out-turned flanges l0 will tend to prevent the cleaning members or bristles readily breaking oli. Furthermore, it will be understood by reference to 2 that the annular `groove 9 being depressed -towards the axis ot the binder 6 will have a tendency to press the bristles more closely together and form the bends or bulges above reerred to, thus preventing any longitudinal movement of the bristles.

Having thus fully described our invention, what we claim as new and desire to secure by Letters Patent, is

l. A brush consisting of a bunch of elon gated crinlrled cleaning elements of. substantially the same length secured intermediate their ends by a band corrugated lengthwise to securely bind said elements.

Q. A brush consisting of a bunch ol elongated erinlrled cleaning elements of substantially the same length secured intermediate their ends by a band corrugated to securely bind said elements.
